Efficient building mortar stirring device

Abstract

The invention provides an efficient building mortar stirring device. The first stirring blade and the second stirring blade are arranged and can be driven by the stirring shaft to rotate, so that the materials can be mixed and stirred. Furthermore, the first stirring blades and the second stirring blades are spiral auger blades, so that when the spiral directions of the first stirring blades and the second stirring blades are opposite, the stirring shaft drives the corresponding first stirring blades and second stirring blades to rotate in the same direction even if the rotating directions are the same; the first stirring blade and the second stirring blade push materials to move in opposite directions. In other words, when the first stirring blades drive the materials to move towards the axis position of the stirring barrel in the rotating process, the second stirring blades drive the materials to move towards the direction, away from the axis, of the stirring barrel in the rotating process. And the two are matched with each other, so that to-be-stirred materials can be stirred in a reciprocating motion manner from inside to outside, the materials can be fully stirred, and the stirring efficiency is improved.

Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and particularly to an efficient building mortar mixing device. Background Art

[0002] In the fields of construction engineering and building mortar production, the building mortar mixing device is one of the core equipment, and its mixing efficiency and uniformity directly affect the quality and construction performance of building mortar. Traditional building mortar mixing devices usually adopt single-direction mixing blades or simple paddle structures. During the mixing process, the material flow direction is single, which easily leads to problems such as uneven mixing and low mixing efficiency. Especially when mixing high-viscosity or large-capacity building mortar, traditional mixing devices often require a long mixing time and are prone to forming dead corners in the mixing barrel, affecting the uniformity of building mortar.

[0003] In the prior art, some mixing devices adopt multi-layer mixing blades or mixing structures at different angles, but there are still problems such as limited material flow direction and insufficient mixing force. For example, although some mixing devices are provided with multiple mixing blades, due to the same blade structure, effective material convection cannot be formed, resulting in poor mixing effects. In addition, the traditional mixing blade design is difficult to achieve the reciprocating movement of materials, so that some materials cannot be fully mixed during the mixing process, affecting the strength and stability of building mortar.

[0004] Therefore, there is an urgent need for a building mortar mixing device that can improve the mixing efficiency and enhance the uniformity of material mixing. The present invention optimizes the design of the mixing mechanism and adopts a first mixing blade and a second mixing blade with opposite spiral directions, so that the material forms a reciprocating movement from the inside to the outside in the mixing barrel, thereby enhancing the mixing effect, shortening the mixing time, and improving the uniformity and quality of building mortar.

In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0025] Figure 1 is a schematic structural diagram of the high-efficiency building mortar mixing device, as Figure 1 shown, and with reference toFigures 2 to 7 , an embodiment of the present invention provides an efficient building mortar mixing device. The efficient building mortar mixing device includes a mixing barrel 100, a mixing mechanism, and a driving mechanism 300. A partition 110 is provided in the mixing barrel 100 to divide the internal space into an upper mixing chamber 140 and a lower driving chamber 150. The upper end of the mixing barrel 100 is provided with a feed inlet 120 and a discharge outlet 130 that communicate with the mixing chamber 140.

[0026] The mixing mechanism is disposed in the mixing chamber 140 and includes a plurality of mixing shafts 210, a plurality of first mixing blades 220, a plurality of second mixing blades 230, a transmission assembly 250, and a mixing main shaft 240. The mixing main shaft 240 is vertically rotatably disposed in the mixing chamber 140 and is coaxial with the mixing barrel 100. The plurality of mixing shafts 210 are circumferentially and evenly distributed along the mixing main shaft 240. One end is rotatably connected to the inner wall of the mixing chamber 140, and the other end is connected to the mixing main shaft 240 through the transmission assembly 250 to drive the mixing shaft 210 to rotate when the mixing main shaft 240 rotates. Both the first mixing blades 220 and the second mixing blades 230 are spiral auger blades, and the spiral directions of the first mixing blades 220 and the second mixing blades 230 are opposite. One first mixing blade 220 or one second mixing blade 230 is fixedly installed on the mixing shaft 210. The driving mechanism 300 is installed in the driving chamber 150, and the driving mechanism 300 is connected to the mixing main shaft 240.

[0027] Specifically, the feed inlet 120 is in a flared shape to facilitate the introduction of materials from the feed inlet 120 into the mixing chamber 140 of the mixing barrel 100. Further, the partition 110 divides the mixing barrel 100 into the mixing chamber 140 and the driving chamber 150, which can make the mixing operation independent of the driving mechanism 300 in the driving chamber 150, thereby preventing the driving mechanism 300 from being corroded and facilitating the maintenance of the driving mechanism 300.

[0028] Further, the first mixing blades 220 and the second mixing blades 230 can rotate under the drive of the mixing shaft 210, thereby being able to mix and stir the materials. Further, since both the first mixing blades 220 and the second mixing blades 230 are spiral auger blades, when the spiral directions of the first mixing blades 220 and the second mixing blades 230 are opposite, even if the mixing shaft 210 rotates in the same direction, the corresponding first mixing blades 220 and the second mixing blades 230 are driven to rotate in the same direction, so that the directions in which the first mixing blades 220 and the second mixing blades 230 push the materials to move are opposite. That is to say, when the first mixing blades 220 rotate to drive the materials to move towards the axial center position of the mixing barrel 100, the second mixing blades 230 rotate to drive the materials to move away from the axial center of the mixing barrel 100. The cooperation of the two can make the materials to be mixed move reciprocally from the inside to the outside, thereby being able to fully stir the materials to improve the mixing efficiency.

[0029] Further, two adjacent stirring blades are a first stirring blade 220 and a second stirring blade 230 respectively, so that the material can reciprocate between the two stirring blades and form a region similar to a vortex region, thereby further fully mixing the material and preventing the generation of dead corners during stirring. Specifically, the number of stirring shafts 210 is four, and the number of both the first stirring blades 220 and the second stirring blades 230 is two.

[0030] During operation, the material to be stirred is introduced into the stirring chamber 140 from the feed inlet 120. The driving mechanism 300 is started, and the driving mechanism 300 drives the stirring main shaft 240 to rotate through the transmission assembly 250. The rotation of the stirring main shaft 240 drives a plurality of stirring shafts 210 to rotate synchronously. The rotation of the stirring shafts 210 drives the corresponding first stirring blades 220 and second stirring blades 230 to rotate. When the first stirring blade 220 rotates, the first stirring blade 220 pushes the material inward. When the second stirring blade 230 rotates, the second stirring blade 230 pushes the material outward. After the material is stirred for a preset time, the material is discharged outward from the discharge outlet 130.

[0031] In this embodiment, the driving mechanism 300 includes a driving motor. The driving motor is fixedly arranged in the driving chamber 150, and the output shaft of the driving motor is connected to the stirring main shaft 240 to drive the stirring main shaft 240 to rotate when the driving motor is started.

[0032] In this embodiment, a plurality of rotating bearings 260 are arranged on the inner wall of the stirring barrel 100, and the other end of the stirring shaft 210 is installed on the rotating shaft bearing 260.

[0033] In some embodiments of the present invention, as Figures 3 to 6 shown, the partition plate 110 is inclined, and the discharge outlet 130 communicates with the lowest position of the inclined surface of the partition plate 110. The high-efficiency building mortar stirring device further includes a crushing mechanism. The crushing mechanism includes a plurality of crushing components and a crushing shaft 420. The crushing shaft 420 is rotatably inserted on the partition plate 110 and is perpendicular to the partition plate 110. The upper end of the crushing shaft 420 is connected to the lower end of the stirring main shaft 240 through a universal shaft, and the lower section is connected to the driving mechanism 300. A plurality of crushing components are evenly distributed along the circumferential direction of the crushing shaft 420. The crushing component includes a crushing rod 411 and a plurality of crushing pieces 412. The crushing rod 411 is parallel to the partition plate 110 and one end thereof is fixedly connected to the crushing shaft 420. A plurality of crushing pieces 412 are arranged at intervals along the length direction of the crushing rod 411, and a vertical edge with a crushing edge is arranged on the crushing piece 412.

[0034] Specifically, the crushing rod 411 rotates along the axis of the partition plate 110 under the rotation of the crushing shaft 420, so as to drive the crushing piece 412 to stir in the stirring cavity 140. Further, there is a clearance fit between the crushing rod 411 and the partition plate 110, so that the crushing rod 411 is located at the bottom of the stirring cavity 140, so as to stir the materials at the bottom of the stirring cavity 140 when the stirring rod rotates and prevent them from settling. Further, one vertical edge of the crushing piece 412 is provided with a crushing edge, which can make the crushing piece 412 have a crushing effect on the agglomerated materials during the rotation of the crushing rod 411.

[0035] Further, the inclined setting of the partition plate 110 can form an inclined plane for the materials towards the bottom of the stirring cavity 140, and since the discharge port 130 is communicated with the lowest position of the inclined plane of the partition plate 110, it is convenient for the materials to be discharged outwards from the discharge port 130. Further, since the crushing shaft 420 is perpendicular to the partition plate 110, the crushing shaft 420 rotates obliquely, so that the crushing shaft 420 is connected to the output shafts of the stirring main shaft 240 and the driving motor through a universal shaft.

[0036] In some embodiments of the present invention, as Figure 6 shown, the crushing piece 412 is perpendicular to the crushing rod 411, and the crushing piece 412 is inclined along the length direction of the crushing rod 411. Two adjacent crushing pieces 412 are mirror images of each other.

[0037] Specifically, the opposite inclination directions of two adjacent crushing pieces 412 can make the two crushing pieces 412 form an "eight" - shaped structure. The front of the rotation direction of the two crushing pieces 412 is the front end of the "eight" shape, and the cutting edges are located at the vertical edges of the front ends of the two crushing pieces 412. When the agglomerated materials contact the cutting edges of the two crushing pieces 412, due to the opposite inclination directions of the two crushing pieces 412, the agglomerated materials can be subjected to oblique cutting forces in opposite directions, so as to increase the crushing efficiency of the agglomerated materials.

[0038] In other embodiments, the crushing piece 412 has two inclination directions. One inclination direction is that the crushing piece 412 is inclined on the crushing rod 411, and the lower edge of the crushing piece 412 is located in front of the upper edge, so that during the rotation of the crushing piece 412, the materials at the bottom of the stirring cavity 140 can be conveyed and stirred upwards along the inclined plane. The other inclination direction is inclined along the length direction of the crushing rod 411.

[0039] In some embodiments of the present invention, as Figure 6As shown, at least one of the two side surfaces of the broken piece 412 is an arc surface. Specifically, the front side surface of the broken piece 412 along the rotation direction of the breaking shaft 420 is only an arc surface. The arc surface can make the speeds of the materials passing through the two side surfaces of the broken piece 412 inconsistent, so that after the materials pass through the broken piece 412, the materials passing through the two side surfaces collide and fuse due to the inconsistent speeds, thereby further improving the mixing and stirring efficiency of the materials.

[0040] In some embodiments of the present invention, as Figure 5 shown, the transmission assembly 250 includes a lower bevel gear 252 and a plurality of stirring bevel gears 253. The lower bevel gear 252 is fixedly arranged at the upper end of the stirring main shaft 240. Each stirring bevel gear 253 is fixedly arranged at the other end of the stirring shaft 210 and meshes with the lower bevel gear 252.

[0041] Specifically, the arrangement of the stirring bevel gear 253 and the lower bevel gear 252 can change the rotation direction of the stirring main shaft 240 in the vertical direction to the rotation direction in the horizontal direction.

[0042] In some embodiments of the present invention, as Figure 3 and Figure 7 shown, a screen plate 160 is arranged in the stirring barrel 100. The screen plate 160 is located above the stirring mechanism. A pressing groove 170 is arranged on the inner wall of the stirring cavity 140. The outer circumference of the screen plate 160 is inserted into the pressing groove 170 so that the screen plate 160 can slide up and down in the pressing groove 170. An elastic member 180 is arranged between the screen plate 160 and the pressing groove 170.

[0043] Specifically, the pressing groove 170 is an annular groove. When the screen plate 160 is pressed down by the weight of the material, the screen plate 160 moves downward and vibrates under the action of the elastic member 180, thereby improving the screening efficiency of the material. Further, the elastic member 180 is a spring.

[0044] In some embodiments of the present invention, as Figure 3 and Figure 4 shown, the high-efficiency building mortar stirring device further includes a material distribution mechanism 500. The material distribution mechanism 500 includes a material distribution rod 510 and a material distribution shaft 520. The material distribution shaft 520 is vertically and rotatably inserted on the screen plate 160. The lower end of the material distribution shaft 520 is connected to the stirring main shaft 240 through the transmission assembly 250. The material distribution rod 510 extends along the radial direction of the screen plate 160, and the inner end is fixedly connected to the material distribution shaft 520. The material distribution rod 510 is in clearance fit with the screen plate 160, and the cross section is trapezoidal, and the inclined surface of the material distribution rod 510 is located on the front side of the material distribution rod 510 along the rotation direction of the material distribution shaft 520.

[0045] Specifically, the material distribution shaft 520 rotates to drive the powder rod to rotate synchronously. The material distribution rod 510 can flatten the materials accumulated on the sieve mesh plate 160 and accelerate the screening of the materials by the sieve mesh plate 160. Further, the inclined surface of the material distribution rod 510 can improve the efficiency of flattening the materials on the sieve mesh plate 160. At the same time, it is convenient for materials larger than the gap between the material distribution rod 510 and the sieve mesh plate 160 to cross the gap along the inclined surface of the material distribution rod 510 and exert a downward pressure on the sieve mesh plate 160, causing the sieve mesh plate 160 to move downward and the elastic member 180 to contract and store energy. When the granular materials completely cross the material distribution rod 510, the elastic member 180 resets and elongates, and the sieve mesh plate 160 moves upward, so that the sieve mesh plate 160 can produce a vibration effect.

[0046] In this embodiment, an upper bevel gear 251 is provided at the lower end of the material distribution shaft 520, and the upper bevel gear 251 meshes with the stirring bevel gear 253.

[0047] In some embodiments of the present invention, as Figure 7 shown, an emergency stop switch is provided at the bottom of the downward pressure groove 170. When the sieve mesh plate 160 moves downward a preset distance along the downward pressure groove 170, the emergency stop switch is triggered.

[0048] Specifically, when the downward pressure received by the sieve mesh plate 160 reaches the preset pressure value, the sieve mesh plate 160 moves downward a preset distance to contact the emergency stop switch, so that the driving motor stops working to prevent the device from being stuck.

[0049] In some embodiments of the present invention, as Figure 4 shown, a plurality of material distribution cones 530 are provided on the material distribution rod 510. The plurality of material distribution cones 530 are evenly distributed along the length direction of the material distribution rod 510, and the material distribution cones 530 are provided on the front side of the material distribution rod 510 along the rotation direction of the material distribution shaft 520. Specifically, the tip of the material distribution cone 530 can break the materials during its rotation.

[0050] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, a discharge plate 131 is provided at the discharge port 130; the discharge plate 131 is used to control the opening and closing of the discharge port 130.

[0051] At this point, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, still, many other variations or modifications that conform to the principles of the present invention can be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
